A survey by an Opticians group claims that excessive use of digital screens could all be having an impact on our eye health, according to a new awareness campaign.
The Think About Your Eyes "Seeing Blue" initiative aims to make people aware of the impact "blue light" could be having on long-term eye health.
It reveals research findings from The Paris Vision Institute that suggest exposure to bad light, sent out by most computers, tablets, smart phones and flat-screen TVs, can damage the cells in our eyes.
Although we need some "good" blue light (Blue-Turquoise) to help regulate our biological clock (sleep/wake cycles, memory and brain performance), prolonged exposure to "bad" blue light (Blue-Violet) could potentially put us at risk of age-related macular degeneration (AMD), a leading cause of blindness -- according to the survey.
Optician, Andy Hepworth, warns: "Most of us don't realise that days spent glued to our smart phones and computers, followed by evenings on the laptop or slumped in front of the TV could pose a risk to our eyes. With our kids increasingly hooked on social media or gaming, we need to think about protecting the whole family - especially with younger generations set to live longer than ever before.
"This is just the tip of the iceberg too. Our whole lighting landscape has changed with energy-saving light bulbs and modern lighting systems, at work, home and school, all radiating potentially harmful blue light that we can't avoid."
Newly launched Crizal Prevencia lenses, are the first to let "good" Blue-Turquoise light in and filter out "bad" Blue-Violet light.
